2 Claims.

Yent invention are adapted for extracting samples of various differentsubstances, but `for the purposes of illustration a sampling deviceconstructed in accordance with my invention will be .described as usedin connection with the extracting of samples of resin from barrels. Itwill be understood, however, that devicesV accordance with my inventionmay be used for extracting .samples of other substances fromcontainersin. general.

Heretofore the practice generally followed in `extracting samples of-rosin from barrels has .been

`to remove the top of the :barrel and to vbreak out va sample from thetop of the resin containedV in the barrel. `This practice isobjectionable in that vafter 4the rosin at .the top ofthe barrel is.broken for permitting the removal -of a .sample vand the topboards ofthe .barrel replaced, rain water is .apt to kfind its Way into thebarrel and to spoil the resin. Furthermore, kbreaking vof therosin .atthe ,topof the barrel followed by replacing the Ybarrel top more or lessloosely results in loss Vofsome of the broken rosin when the barrel ismoved around.

In .accordance with my invention, I extract a clean, true Vsample'from abarrel or other .container through a small opening in ,thecontainenwhich opening normally -is covered by a closure which is adapted to beremoved and replaced easily.

An object of my invention is to provide an improved device forextracting samples from a barrel or the like in the manner generally setforth above, i. e., in such a way as to dispense with the necessity ofremoving the top of the barrel. Another object is to provide a device ofa character referred to by means of which a clean, smooth, truelyrepresentative sample may be extracted without its being subject to themarring action of a cutting tool or to unusual conditions, such as localheating which, if present, would change the properties of the sample soas to render the latter different from the contents of the container.Other objects will become apparent from a reading of the followingdescription, the appended, claims, and the accompanying drawing, inwhich:

. By way of illustration a preferredembodiment of my improved samplingdeviceis illustrated in 2) 9 `connection with a barrel A providedwithatop filler openingv i, and Withan :aperture :2 its side wall.. Thesampling .device generally .designated B comprises a' hollowsamplereceiving-.part

3 ,of considerably .smaller .c ross .section than .the l2.5 aperture 2and r`a1 pair fof supporting vparts .or 'v arms ,ii-.t extendinglaterallyfrom ythe'.. s.,arn ple receiving part 3 and being ladapted to`be I secured to the side wallof the barrel adjacent to, the

`aperture 2 for supporting the sample-rece' Ing i30 part 3 in the.barrel in spaced relation'-tpfthe lperiphery of the `aperturelfand 1 inVsubeta,ntial axial alignment with the latter. Preferably, thesupporting arms 4 include portions 5 adapted to lie against the wall ofthe aperture 2 and flanges 6 adapted to lie against the outside of thecontainer Wall immediately adjacent the aperture 2.

The sample-receiving part 3 may comprise two separable sections 3a and3b adapted to be assembled as in the illustrated form by telescoping onewithin the other. As shown the section 3b is adapted to be settelescopically within the section 3a.

It will be understood that it is desirable that the sampling device beso arranged that the sample .can be removed easily therefrom after thedevice itself has been removed from the barrel, and to this end thesections 3a and 3b preferably are constructed in such manner that theirrespective walls may be sprung apart somewhat for releasing the sample.In the illustrated form the section 3a comprises a back Wall 1, twoYside wa1ls`8--8, and anges 9-9 extending along'the forward edges of theside walls, but terminating in spaced relation one from the other.

sides in the provision of an expansible samplereceiving part whose wallsmay be sprung apart relatively outwards from the sample to release thelatter without breaking it.

In use, the sampling device B is inserted through the aperture 2 andpositioned as shown best in Figure 2 with the supporting parts IIholding the sample-receiving part 3 in the position shown and lthe wall`1 of the section 3a closing the space between the free edges of theflanges II of the channel-shaped section 3b. In order to close theaperture 2 a spring metal cap closure I2 is inserted in the aperture andnails or other fastening means are driven through the cap and preferablythrough the supporting parts II and into the barrel wall. The containeris then filled through the top opening I, which then is closed by anysuitable means. When the molten rosin is poured into the barrel it, ofcourse, will ll the hollow part 3 of the sampling device which is openat both of its ends, thus permitting it to be filled readily.

In order to obtain a true sample of the hardened rosin the nails I3 arewithdrawn and the ,closure I2 is removed. The supporting arms 4 are thenbent outwardly into parallelism with the axis of the sample-receivingpart 3 as shown in Figure 6. Thereafter the rosin surrounding thesample-receiving part 3 is loosened by means of a hollow cutting tool I4which is of greater diameter than thesample-receiving part 3 and whichis of slightly smaller diameter than the aperture 2. This will permitthe sampling de- 1 vice to be removed bodily from the barrel after whichthe sections 3iL and 3b are separated and 'the clean, smooth, truesample is dislodged from the section 3b or the section 3a as the casemay be.

jItA is apparent that a sample obtained in this manner will be trulyrepresentative of the rosin within the barrel since the sample has notbeen subjected to any cutting action, heating, or other modifyingconditions.

By the use of my device it is unnecessary to remove the top of thebarrel and to break the rosin therein in order to secure a sample. Ithus eliminate the damage to the rosin caused by rain water seepingthrough the top head and lying on the broken rosin. Furthermore, byusing my device there will be no loss of broken rosin sifting outthrough cracks in and around the rhead' where barrels are rolled orhandled. The timer necessary to obtain a sample and hence the expense ofsampling is greatly reduced. Since it is unnecessary to remove thebarrel top in order to obtain a sample, it is possible to construct thebarrel in such a manner that the top ts into a croze in the same manneras the bottomwhereby the barrel is greatly strengthened. With thisconstruction, if the barrel is stored for any length of time and if thebottom shows a tendency to rot, the barrel may be up-ended so as toposition the top wall underneath and in this way the barrel will remainin good condition for a much longer time thanV when the barrels rest ontheir bottom heads only during the entire time they are in storage. Y

Although av practical and the at present preferred form of my inventionhas been shown and described for the purposes of illustration, it willbe understood that Various modications may be made in the specificconstruction and arrangement of the parts without departing from theinvention as denedin the claims.

I claim:

l. The combination with a container having a wall with an aperturetherein; of a sampling device including a hollow part of less crosssectional width than said aperture positioned in said con- :tainer inaxial alignment with said aperture for receiving a sample; a supportingarm extending from said hollow part to said wall and being securedthereto for supporting said hollow samplereceiving part in saidcontainer in alignment with said aperture in spaced relation with theperiphery thereof, said supporting arm being adapted to be bentoutwardly into substantial parallelism with the axis of said aperture topermit use of a hollow cutting tool for removing said device from saidcontainer; and a closure for said aperture iitting over said device andbeing detachably secured to said container. A

V2. A combination as set forth in claim-l in which the hollowsample-receiving part comprises two separable sections.
